| Abstract: | Aerogels have special thermal conduction manners which are different with common materials, because of their unique structures. The theoretic formulas of aerogels including solid conductivity, gas conductivity and radiative conductivity are analysed. According to these formulas, the methods of minimizing thermal conductivity of aerogels are discussed which are the references of preparing super insulation materials. The applications and the development are forecasted. |
